1. System Preference > Sound

   Make sure that "Mute" is not enabled.

2. If you see red light in the headphone port, plug the headphone into and out of the port.

     That will flip the microswitch inside the port. Sound may be stuck in the digital mode.


3. Reset PRAM.  http://support.apple.com/kb/PH4405
